Broadcast captioning jobs involve transcribing everything that is spoken during live TV programming. In these jobs, you provide realtime captions using a stenotype machine or similar device, trying to type exactly what the speaker in the show is saying at the time, such as news anchors, sportscasters, commentators, interviewers, and interviewees. Some types of broadcasts that closed captioners work on include news shows, emergency broadcasts, sports events, talk shows, special engagements, and interviews. You also type information such as the identity of the speaker (if not on camera), sound effects, and other relevant information during live broadcasts, and may be asked to add closed captioning to other events before the recorded broadcasts are replayed.
